Jerry, Thank you very much! The billboard reefers are some K-Line and some Atlas-O. I would like to buy more, but they can be pricey!! I have 1/4" cork roadbed down, which looks you have something similar. The noise isn't bad. The outer loop is GarGraves, and the inner is some 0-27 tubular I had with 042 curves I bought. My original plan was for one track, and I didn't figure in on shelving at the corners. Then over one winter when I couldn't work on it because of carpal tunnel problems, I decided two tracks would work, so I tried the second loop with tubular. The plan was to go back and fix the corner shelves, but now that I see double track doesn't work on the two walls with jogs, I will only have one corner with double track and will fix only that one.
Here is a video of an MTH set running. I had to slow down for the jogs on the unseen walls.
Here is another. It shows the jogs I mentioned earlier.
